Design and Simulation Based Studies of a Dual Band Antenna for WLAN/WiMax Application

Scientific Study from the year 2012 in the subject Engineering - Communication Technology, Indian Institute of Technology, Delhi, course: M.tech, language: English, abstract: Two different designs of a dual band patch antenna have been investigated in this paper. By using u-slot patch geometry dual band operation has been obtained. The patch antenna is simulated by Ansoft HFSS software which is finite element method based simulator. After the antenna performance characteristics such as, input impedance, return loss, polar plot are obtained.. This observation has provided us sufficient insight to optimize the antenna parameters to meet the design requirements. The proposed designs of the antenna operate in 2.4 GHz band which is common to all two designs but the second operating band is different. By varying the slot broadness the second frequency band can be shifted IEEE802.11b (2.45 GHz) and IEEE802.11y (3.2 GHz) standards which would allow WLAN operation. This patch antenna has been intended to be used in portable devices that demand miniaturized constituent parts.
